The death toll in Japan is up to 9,079, with another 12,645 missing, according to officials. The 9.0-magnitude earthquake struck off the coast of Japan on March 11, and triggered a devastating tsunami that has left at least 400,000 people homeless and hungry. The damage is expected to exceed $200 billion.

The American Red Cross is accepting donations from those who want to assist in first aid, assessment, recovery and rehabilitation. Those who want to help can go to www.redcross.org and donate to Japan Earthquake and Pacific Tsunami. People can also text REDCROSS to 90999 to make a $10 donation to help those affected by the earthquake in Japan and tsunami throughout the Pacific.
